Question 15

Please read the following scenario then answer the following question(s).
Molecular biologists have perfected DNA fingerprinting so that it is possible to use the technique to provide evidence to solve crimes and even identify a child's parents. Recently, a U.S. immigrant asked the U.S. Citizenship and Immigration Services for permission to have her young daughter who was living with grandparents in their homeland join her.Her request was denied because there was an apparent mix-up with the child's birth certificate and it could not be used as proof of maternity. Proof is required in cases such as this. The mother requested DNA fingerprinting to make her case. Samples of DNA were taken from the mother (Mom) and daughter (D1) as well as from another daughter (D2) and a son (S) living in the United States with her. Tandem repeat analysis was run on the four samples, and the results are shown here.
